The storm drainage rate increase coupled with previously publicized sewer rate increases being proposed over the same stretch of time would add up to an additional $25.44 on yearly utility bills for the typical residential home in Sioux Falls in 2020, the first year the increases would take effect.

For the 2,700 users of the city's electric utility, their yearly electricity bill would jump by an average of about $22.

Those projections are based on calculations provided by the Public Works Department, compiled as a part of its yearly rate analysis.

Cotter said the proposed increases, which the City Council will be asked to sign off on next month, are necessary to keep up with demands on the utility infrastructure networks that wear and tear along with a growing population bring.

For sewer rate increases, users would see rates jump up 6 percent in 2020, 5 percent in 2021, 4 percent in 2022 and 3 percent in 2023. Storm drainage fees would go up 5.4 percent in both 2020 and 2021, 4.4 percent in 2022, and 3.4 percent in 2023.

Electric customers of the city would see rates go up 3 percent each year between 2020 and 2023.
